JOURNAL-BEARING.

EBPECIFICATION forming part of Letters Patent No. 318,334, dated May 19, 1885.

Application filed February 10, 1885. (No model.)

To all whom/it may concern.-

Be it known that I, ALvIs MARTIN WEATH- ERLY, a citizen of the United States, residing at Selma, in the county of Dallas and State of Alabama, have invented certain new and useful Improvements in Journal Bearings, of which the following is a description.

This invention relates to that class of de vices which are used to serve as substitutes for solid metal in journal-bearings; audits object is to provide a porous compound substance of sufficieut density to support the required weight without yielding so much as to be impracticable. To this end my invention consists in the construction and combination of parts forming a journal-bearing, hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a transverse vertical seotion,and Fig. 2 is a longitudinal vertical section, of a journal-bearing corresponding to my invention.

A represents a box of brass or other metal, provided,as usual,with flanged edges B to retain the lining. It has been common heretofore to line journal-boxes with soft'metal composition; butsueh soft metal, when once shaped, remains in that shape until it is worn out of shape innse. It is not in any respect elastic or yielding to the form of the journal. For this permanent metal I substitute asbestus,O, in a fibrous condition compressed into the box to such a degree as to form abearing sufficiently rigid to prevent the weight resting on the journal from pressing the journal against the box at D. Fibrous asbestus will admit this degree of-compression without losing its elasticity and without losing its porosity. I partially fix the asbestos in the form fitting the journal by mixing and intimately combining therewith white lead and oil of the consistence in which white lead is usually sold on the market for a paint. The oil in the paint will at first serve as a lubricator,and when this oil is driven out by the lubricating-oil which is in general use the lead will not become rigid and dry, and the combined asbestus and lead will still be sufficiently porous, so that the oil ping the passage of oil in bearings subject to great weightsuch as in'the journals of enginewheelsI provide a'series of brass or other metallic oil-tubes, E, extending from the box A nearly through to the inner face of the asbestus and lead 0 toward the journalbearing. Through these tubes the oil may be introduced, as usual, and when it enters the bearing proper will soak it up.

Other fibrous materialsuch as cotton waste-has before been used as a mere wick to draw oil up from a reservoir below to a journal; but such fibrous material did not serve in any respect as a bearing for the journal, and it would be impossible for such fibrous material to serve this :purpose, from the fact that the friction and pressure of the journal on the cotton in service would quickly ignite the cotton. For this reason asbestus as a noncombustible fibrous material is indispensable to my invention. My bearing maybe placed either side up, so as to rest upon the journal, or so as to support the same in order that it may be adapted for use with car-wheel journals, or with shafting, &c.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of a metallicbox, A,a series of oil-tubes, E, extending within the box from its exterior, and a composition of asbestus and white lead filling the box between the tubes and shaped on its inner face, substantially as described, to constitute a journal-bearing.
